2023-06-30pid: Replace struct pid 1-element array with flex-arrayKees Cook
For pid namespaces, struct pid uses a dynamically sized array member, "numbers". This was implemented using the ancient 1-element fake flexible array, which has been deprecated for decades. Replace it with a C99 flexible array, refactor the array size calculations to use struct_size(), and address elements via indexes. Note that the static initializer (which defines a single element) works as-is, and requires no special handling. Without this, CONFIG_UBSAN_BOUNDS (and potentially CONFIG_FORTIFY_SOURCE) will trigger bounds checks: https://lore.kernel.org/lkml/20230517-bushaltestelle-super-e223978c1ba6@brauner Cc: Christian Brauner <brauner@kernel.org> Cc: Jan Kara <jack@suse.cz> Cc: Jeff Xu <jeffxu@google.com> Cc: Andreas Gruenbacher <agruenba@redhat.com> Cc: Daniel Verkamp <dverkamp@chromium.org> Cc: "Paul E.

2023-06-30kdb: Handle LF in the command parserDouglas Anderson
The main kdb command parser only handles CR (ASCII 13 AKA '\r') today, but not LF (ASCII 10 AKA '\n'). That means that the kdb command parser can handle terminals that send just CR or that send CR+LF but can't handle terminals that send just LF. The fact that kdb didn't handle LF in the command parser tripped up a tool I tried to use with it. Specifically, I was trying to send a command to my device to resume it from kdb using a ChromeOS tool like: dut-control cpu_uart_cmd:"g" That tool only terminates lines with LF, not CR+LF. Arguably the ChromeOS tool should be fixed. After all, officially kdb seems to be designed such that CR+LF is the official line ending transmitted over the wire and that internally a line ending is just '\n' (LF). Some evidence: * uart_poll_put_char(), which is used by kdb, notices a '\n' and converts it to '\r\n'. * kdb functions specifically use '\r' to get a carriage return without a newline. You can see this in the pager where kdb will write a '\r' and then write over the pager prompt. However, all that being said there's no real harm in accepting LF as a command terminator in the kdb parser and doing so seems like it would improve compatibility. After this, I'd expect that things would work OK-ish with a remote terminal that used any of CR, CR+LF, or LF as a line ending. Someone using CR as a line ending might get some ugliness where kdb wasn't able to overwrite the last line, but basic commands would work. Someone using just LF as a line ending would probably also work OK. A few other notes: - It can be noted that "bash" running on an "agetty" handles LF as a line termination with no complaints. - Historically, kdb's "pager" actually handled either CR or LF fine. A very quick inspection would make one think that kdb's pager actually could have paged down two lines instead of one for anyone using CR+LF, but this is generally avoided because of kdb_input_flush(). - Conceivably one could argue that some of this special case logic belongs in uart_poll_get_char() since uart_poll_put_char() handles the '\n' => '\r\n' conversion. I would argue that perhaps we should eventually do the opposite and move the '\n' => '\r\n' out of uart_poll_put_char(). Having that conversion at such a low level could interfere if we ever want to transfer binary data. In addition, if we truly made uart_poll_get_char() the inverse of uart_poll_put_char() it would convert back to '\n' and (ironically) kdb's parser currently only looks for '\r' to find the end of a command.

2023-06-30spi: bcm-qspi: return error if neither hif_mspi nor mspi is availableJonas Gorski
If neither a "hif_mspi" nor "mspi" resource is present, the driver will just early exit in probe but still return success. Apart from not doing anything meaningful, this would then also lead to a null pointer access on removal, as platform_get_drvdata() would return NULL, which it would then try to dereference when trying to unregister the spi master. Fix this by unconditionally calling devm_ioremap_resource(), as it can handle a NULL res and will then return a viable ERR_PTR() if we get one. The "return 0;" was previously a "goto qspi_resource_err;" where then ret was returned, but since ret was still initialized to 0 at this place this was a valid conversion in 63c5395bb7a9 ("spi: bcm-qspi: Fix use-after-free on unbind"). The issue was not introduced by this commit, only made more obvious.

2023-06-30x86/efi: Make efi_set_virtual_address_map IBT safeThomas Gleixner
Niklāvs reported a boot regression on an Alderlake machine and bisected it to commit 9df9d2f0471b ("init: Invoke arch_cpu_finalize_init() earlier"). By moving the invocation of arch_cpu_finalize_init() further down he identified that efi_enter_virtual_mode() is the function which causes the boot hang. The main difference of the earlier invocation is that the boot CPU is already fully initialized and mitigations and alternatives are applied. But the only really interesting change turned out to be IBT, which is now enabled before efi_enter_virtual_mode(). "ibt=off" on the kernel command line cured the problem. Inspection of the involved calls in efi_enter_virtual_mode() unearthed that efi_set_virtual_address_map() is the only place in the kernel which invokes an EFI call without the IBT safe wrapper. This went obviously unnoticed so far as IBT was enabled later. Use arch_efi_call_virt() instead of efi_call() to cure that.

2023-06-30ceph: don't let check_caps skip sending responses for revoke msgsXiubo Li
If a client sends out a cap update dropping caps with the prior 'seq' just before an incoming cap revoke request, then the client may drop the revoke because it believes it's already released the requested capabilities. This causes the MDS to wait indefinitely for the client to respond to the revoke. It's therefore always a good idea to ack the cap revoke request with the bumped up 'seq'.

2023-06-30ceph: trigger to flush the buffer when making snapshotXiubo Li
The 'i_wr_ref' is used to track the 'Fb' caps, while whenever the 'Fb' caps is took the kclient will always take the 'Fw' caps at the same time. That means it will always be a false check in __ceph_finish_cap_snap(). When writing to buffer the kclient will take both 'Fb|Fw' caps and then write the contents to the buffer pages by increasing the 'i_wrbuffer_ref' and then just release both 'Fb|Fw'. This is different with the user space libcephfs, which will keep the 'Fb' being took and use 'i_wr_ref' instead of 'i_wrbuffer_ref' to track this until the buffer is flushed to Rados. We need to defer flushing the capsnap until the corresponding buffer pages are all flushed to Rados, and at the same time just trigger to flush the buffer pages immediately.
